A Note on the Grandfather Paradox

Issue: • Author/s: Brian Garrett
Topics: Epistemology, Metaphysics, Ontology

In this note, I am critical of some aspects of David Lewis’s resolution of the Grandfather Paradox. In particular, I argue that Lewis gives the wrong explanation of Tim’s inability to kill Grandfather, and that the correct explanation makes essential reference to the self-undermining character of Tim’s grampicide.
